Posted:15th Feb 2006I just figured you guys might have a good idea as to where I can find these two chemicals. It's not for poi or firebreathing, so you don't need to bother with any safety lectures (I don't even have any fire toys yet, still waiting on one of my friends who makes fire staves to get around to it).

Posted:16th Feb 2006if you have listerine or other high-alcohol mouthwashes there, you can fill ice cube trays with it, wait for the water to freeze and pour off the alcohol on top. hell, it might work even better with cheap vodkas too. slightly less water to freeze off

Posted:16th Feb 2006Do you need to have any form of chemical licence to receive goods from Sigma Aldrich? I would have thought there'd be some kind of problem, since Petroleum Ether burns and boils at very low temperatures.

The reason I need it is because I'm making a tincture of various herbs (primarily ginseng), to see if I can successfully create a tincture that could be watered down and sold as a health-conscious alternative to standard energy-RTDs. The reason I need Petroleum Ether is that many of the herbs require "defatting" in order to absorb the correct parts of the herb rather than the parts that would potentially contaminate the final tincture.

Also, just for the record, There is no one boiling point for Pet. Ether. When you purchase it, you purchase the one with the size of alkane chains you need to fit the range you want it to boil at. Yes, you can get it with a boilsing point of forty degrees, but you can also get it with a boiling point of 120.

<edit> Also (i've just remembered this), Please note that Sigma's chemicals (and most other chemical suppliers) aren't seen as suitable in use for medical applications or drug preparations. If you do want medical grade pet. ether though, it will cost you an absolute fortune.EDITED_BY: ducky2108 (1140087075)

Ancient wiseman say "It is very strange person, who, when left alone in room with teacosy, does not try it on"

If we as members of the human race practice meditation, we can transcend our fear, despair, and forgetfulness. Meditation is not an escape. It is the courage to look at reality with mindfulness and concentration. Thich Nhat Hanh
